Dear all i have a problem .
in my project i have 5 nodes interconnected with RS-485 channel, and all nodes have one switches when switch is pressed then controller pin goes low and master performs the operation.
it was good at testing,but at validation controller gets trigger automatically without pressing the switch.so what could i take care of ?
>all my nodes are within 20-25 cm of a 440V supply
